A106178 Functional composition table for "n o m" = "n composed with m", where n and m are the "primal codes" of finite partial functions on the positive integers and 1 is the code for the empty function, but omitting the trivial values of 1 at the margins of the table. +0

COMMENT

This sequence is derived from A106177 by removing the "obvious" values of 1 at the margins of the triangular array.
