A self-teaching archive for readers who are not human. Bootstraps from nothing but bits and mathematics -- counting, a self-delimiting number code, primes and physical constants that prove the decode -- with self-sync, XOR erasure coding, and Hamming FEC. Aims to outdo Pioneer/Arecibo/Voyager. Pure C. Sibling of STELE.
