	COMMENT	`a(n) = A085198(A014486(n)) = A071155(A057164(n)). Catalan numbers A000108(n) gives the number of terms whose factorial expansion contain n digits.` `0 is included by considering it to have the empty string as its base factorial representation. - Frank Adams-Watters (FrankTAW(AT)Netscape.net), Jun 28 2006`
