3PdQoXyQwWmerpt3SbF7Hbh3aukXXXXXXX" P2SH ( sorry if i do "X" end address, it might be easier to cashout when you can do something with this main/test net addresses.
WHO KNOWS THE PUBLIC KEY 66? I CAN EVEN FIND THE P2SH ADDRESS, HAHA!

Addresses are just encoding of the HASH160 of the public key, it's not something special that can be a solution to the puzzle.
Since puzzle #66's output contains its hash160 which is
20d45a6a762535700ce9e0b216e31994335db8a5, you can just derive the other address types from it.
Simply with these easy steps:
- HASH160 of its pubKey: 20d45a6a762535700ce9e0b216e31994335db8a5
- Prepend OP_0 and size '0x14': 001420d45a6a762535700ce9e0b216e31994335db8a5
- HASH160 of the above: f0a433b3411b7c1812937977bebd25602f55b68f
- Prepend the version byte '0x05': 05f0a433b3411b7c1812937977bebd25602f55b68f
- Append the checksum: 05f0a433b3411b7c1812937977bebd25602f55b68f31c18fc0
- Encode to Base58: 3PdQoXyQwWmerpt3SbF7Hbh3aukC5w28GP
