Motivated by an attempt to explain the huge terms in A302656.
a(n) = A377904(n) - A377906(n).

Examples

			For n = 4, 10000 appears as A302656(93) and as A377904(176), so a(4) = 176-93 = 83. As a result, we get A302656(176) = 2*10^1111 - 1 = 199...9 (with 1111 9's).

Summary: the 16 sequences derived from A302656 are A376769-A376776, A377903-A377904, A377906-A377911.

A377910 a(n) = number of digits in A377909(n), or 0 if A377909(n) = -1.
