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.)

234 = 2 * 3² * 13
Thus there are precisely two nonisomorphic abelian groups of order 234,
(1) Z₃ ⊕ Z₇₈
(2) Z₂₃₄
