It's just this recursive formula: \(a(n) = a(n-1) + a(n-4) - a(n-5)\)
Or then rather: \(a(n) = a(n-4) - \left( a(n-5) - a(n-1) \right) \)

Quote:Your formula in post #2 comes out to 14 objects in RPL …

Is this what you refer to?
Code:
\<< 3 OVER * 4 + SWAP
4 MOD 2 - SQ - 2 /
\>>

Quote:You may want to add it to the OEIS page since it is shorter and simpler than the formulas there.

Meanwhile it has been updated.
