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.)

150 = 2 * 3 * 5²
Thus there are precisely two nonisomorphic abelian groups of order 150,
(1) Z₅ ⊕ Z₃₀
(2) Z₁₅₀
