Jon E. Schoenfield: Mostly I wanted to get rid of the old b-file, which was improperly formatted, used the made-up (non-OEIS) term "b-text file", and had other problems.

FORMULA

Appears to satisfy a(n)=1444*a(n-7)+a(n-14)-76*sqrt(a(n-7)*a(n-14)) for n >= 16. For n = 15, 14, 13, ... this would require a(1) = 16, a(0) = 49, a(-1) = 169, ... - Henry Bottomley, May 08 2001; edited by _Robert Israel_, Sep 28 2014
