GlaisherFranklin from IntegerPartition
The Glaisher-Franklin bijection: even part sizes halved become repeated parts, and repeated odd parts merge into their binary multiples.
FindStat's Mp00312. It sends the set of even part sizes, each halved, to the set of repeated part sizes.
Called as CombinatorialMap(x, "GlaisherFranklin"). The head's page has its examples.

Properties
Transport a statistic
Pick a statistic on IntegerPartition. Its distribution over the images of IntegerPartition at each size is computed, and compared with the 165 statistics on IntegerPartition: those that share it are the ones the map sends it to, as far as the sizes computed show.
