Thanks! The part "highly non-trivial" makes me feel better... The paper is beyond fantastic, I must say! Best, jj * James Propp <jamespropp@gmail.com> [Aug 18. 2013 09:12]:

Dear Jim, The bijection is classical, but highly non-trivial. It is a variation on the Hillman-Grassl bijection, itself a variation on RSK. The shortest answer to this question is in my partition bijections survey (see link below), section 9.1. Best, -- Igor

Dear Igor,
Surely you would know of such a thing!

Hesitatingly, I'll dare ask a question of rather specific nature:
The generating function of planar partitions is 1 / prod(n>=1, (1 - q^n)^n ) Now that is also the g.f. of (the usual) partitions with one sort of 1, two sorts of 2, three of 3, etc.
I am the only person on this planet that cannot figure out a (natural, constructive) bijection?
Best, jj
