Comments

"All-interval" means that the differences 11-0=11, 7-11=-4, 4-7=-3, ..., 6-5=1 read modulo 12 contain all numbers (intervals) from 1 to 11.

This is one of 3856 such sequences.

The Anders link contains a source program written in Strasheela, formulated as a constrained satisfaction problem (CSP).
