[seqfan] Q: formula in A054556

[Richard Mathar]

I cannot comprehend the meaning of the formula
   a(n) =A140063 a(n)+n
in http://research.att.com/~njas/sequences/A054556  .
I understand that a(n)=4*n^2-9*n+6 and that A140063(n)=7*n^2/2-15*n/2+5 .
So one could note for example  a(n)=A140063(n)+1+n*(n-3)/2 = A140063(n)+A000217(n-2)
and may similar relations.
Is there only some punctuation, some squares or anything else missing
in the formula?
