Oh, it's a good idea to announce the solution to A007798 and A134939.
Sequence A007798 indeed satisfies the conjectured formula:
A007798(n) = (5^n - 2*3^n + 1) / 4
while sequence A134939 satisfies the following formula:
e(n) = (3^n-1)*(5^n-3^n) / (2*3^(n-1))
A134939(n) = (3^n-1)*(5^n-3^n) / 2
The proof of these formulas will be given in our joint paper with Toby Berger.
Regards,
Max
