31:T7e6,md`# Fallen Transponder Redux I originally has some trouble with this because my data was wrong... However, I figured out the proper pattern and fixed the typos in the original text.... RENDEZVOUS ${transponder} ## Identify Keys There are groups of characters that are either \`(CCnC)\` (where \`C\` represents a letter and \`n\` represents a number) or \`(nnnC)\`... Specifically \`(00nC)\`. I bet groups of the latter represent our key. Let's identify them by using the number that comes before the letter to modify the ascii code represented by the letter by \`-n\`

${Object.keys(transponderKeyTest).map((key,idx) => `${idx}. ${key}: ${transponderKeyTest[key]}`).join('
')}

## Seems like the right track We have -most- of the letters used to spell RENDEZVOUS. Let's do all of the letters from A-Z this way. We'll use \`-5\` as the modifier because all of the "key groups" have 5 has the modifier.

${Object.keys(transponderKeys).map((key,idx) => `${idx}. ${key}: ${transponderKeys[key]}`).join('
')}

## Replace Encrypted Text with Ciphers

${decrypted}

## Hmmm... Not Quite Right Perhaps the pairs of \`nC\` in the \`(CCnC)\` groups should be modified as well. The first one I see is now \`(ZV3L)\`. The word should be \`rendeZVOus\` but is currently \`rendeZVLus\`. But, it turns out \`L+3 = O\`, so let's try that replacement.

${doubleDecrypted}

Then modify the \`((3000)cn)\` groups to add \`number of spaces = n\` and \`c.toUpperCase() + 3\`:

${tripleDecrypted}

Finally, convert all remaining \`(3000)\` groups to a single space:

${quadDecrypted}

## Split into lines

${lines.join('\n')}

It seems to be making a pictogram of some sort, but my decoding still isn't 100% correct... ` 32:T9a7,tripleDecrypted = { const startgrouprgx = /(\d{1,2})$\(3000$([a-z])(\d+)\)/g const grouprgx = /$\(3000$([a-z])(\d+)\)/g const startgroups = new Map() const endgroups = new Map() let matches while((matches = startgrouprgx.exec(doubleDecrypted)) !== null) { startgroups.set(matches[0].replace(/$/g,'\\(').replace(/$/g,'\\)'),{char: matches[2].toUpperCase(), spaces: Number(matches[3]), linenum: matches[1] }) } const startgroupKeys = Array.from(startgroups.keys()) const startgroupsreplaced = startgroupKeys.reduce((str, key) => { console.log('key:', key) const group = startgroups.get(key) console.log('group:', group) const keyrgx = new RegExp(key, 'g') const {linenum} = group const spaces = sequence(group.spaces, _ => ' ').join('') const char = String.fromCharCode(group.char.charCodeAt(0) + 3) const replaceWith = `${spaces}${char}` const newstr = str.replace(keyrgx, `${linenum}:${spaces}${char}`) console.log(newstr) return newstr }, doubleDecrypted) while((matches = grouprgx.exec(doubleDecrypted)) !== null) { endgroups.set(matches[0].replace(/$/g,'\\(').replace(/$/g,'\\)'),{char: matches[1].toUpperCase(), spaces: Number(matches[2]) }) } const endgroupKeys = Array.from(endgroups.keys()) const endgroupsreplaced = endgroupKeys.reduce((str, key) => { console.log('key:', key) const group = endgroups.get(key) console.log('group:', group) const keyrgx = new RegExp(key, 'g') const spaces = sequence(group.spaces, _ => ' ').join('') const char = String.fromCharCode(group.char.charCodeAt(0) + 3) const replaceWith = `${spaces}${char}` const newstr = str.replace(keyrgx, `${char}${spaces}`) console.log(newstr) return newstr }, startgroupsreplaced) return endgroupsreplaced.replace(/3000/g,' ') // const groupKeys = Array.from(groups.keys()) // console.log('groupKeys:', groupKeys) // const nextstr = groupKeys.reduce((str, key) => { // console.log('key:', key) // const group = groups.get(key) // console.log('group:', group) // const keyrgx = new RegExp(key, 'g') // const spaces = sequence(group.spaces, _ => ' ').join('') // const char = String.fromCharCode(group.char.charCodeAt(0) + 3) // const replaceWith = `${spaces}${char}` // const newstr = str.replace(keyrgx, `${spaces}${char}`) // console.log(newstr) // return newstr // }, doubleDecrypted) // return nextstr }33:[] 2f:{"title":"Fallen Transponder Redux","cells":[{"id":0,"value":"$31","pinned":true,"hidden":false,"mode":"ojs"},{"id":290,"value":"md`${transponder}`","pinned":true,"hidden":false,"mode":"ojs"},{"id":354,"value":"transponderKeyTest = {\n const keyrgx = /\\(00(\\d)([A-Z])/g\n const keys = []\n let matches\n while((matches = keyrgx.exec(transponder)) !== null) {\n const original = matches[2]\n const modifier = Number(matches[1])\n const cipher = String.fromCharCode(original.charCodeAt(0) - modifier)\n keys[original] = cipher\n }\n return keys\n}","pinned":true,"hidden":false,"mode":"ojs"},{"id":372,"value":"transponderKeys = sequence(26, x => String.fromCharCode(x+65)).reduce((agg, char) => ({...agg, [char]: String.fromCharCode((char.charCodeAt(0) - 65 + 21) % 26 + 65)}),{})","pinned":true,"hidden":false,"mode":"ojs"},{"id":365,"value":"decrypted = transponder.split('').map(\n char => !!transponderKeys[char] ?
