Abelian Non-isomorphic Classes Lister

List all non-isomorphic abelian classes for natural numbers from 2 to 239

Please enter a number between 2 and 239 [inclusive].
The isomorphism classes of your number will then be listed.
(You can also simply hit "Find Groups" to have a number chosen at random.)

196 = 22 * 72
Thus there are four nonisomorphic abelian groups of order 196,
(1) Z14 ⊕ Z14
(2) Z2 ⊕ Z98
(3) Z7 ⊕ Z28
(4) Z196

  1. Determines factorization of number
  2. Determines type of options to arrange factors
  3. Determine all combinations
  4. Check against numerical prediction of types for groups
