Anyone interested in writing some lines of Haskell code for generating the Zumkeller numbers? 


My C/C# solutions looks clumsy (but is fast). I think this can be done much more elegant in Haskell with lazy evaluation.

Not related to Haskell, but do you think semi-Zumkeller numbers are semi-perfect numbers? Maybe some Haskell code for testing it for some numbers?
