[seqfan] Re: Self-stuffable numbers

I'm replying from my phone so maybe this reply won't be in the correct sequence.
My question of terminating digit being 0,2,6 referred to self stuffable numbers, and not roots.
So I think that 21 thing, which is a root and not a term of the main sequence, introduces no contradiction.
The 21 number becomes a term only when terminating with 0, right?

A322323 has been restored to previous state.  Thanks for finding a couple of new primitive roots.
