A002182(A002182(n))

[Jonathan Post]

Dear Tony,

I trust your judgment on what is beautiful versus what is contrived.  So I
won't submit the sequence, unless and until (unlikely)  someone on seqfans
finds something of interest in it or near it. Good b-list by you, in any
case.  At worst, a b-list allows people to find new things beyond their
computational power.  Some are contrived, some are cool. Thanks again for
the good advice.
