RPL mini-challenge - Triangle of Primes (HP-49G/G+,50g)

[Paul Dale]

The 34S version is going to be difficult to beat. Eighteen steps without the initial LBL and the END. Everything is on the stack and no labels or extra registers needed.

For a moment there, I thought that steps 5 and 6 could be combined using the [<->] shuffle command. Alas, no. They need to be separate steps.

I think steps 3 and 4 might possibly be contender for combining.
