Best Answer

There are five groups of order 8: three of them are Abelian and the other two are not.

These are

1. C8, the group generated by a where a8 = 1

2. C4xC2, the group generated by a and b where a4 = b2 = 1

3. C2xC2xC2, the group generated by a, b and c where a2 = b2 = c2= 1

4. the dihedral group

5. the quaternion group

Q: What is the numbers of groups of order 8 upto isomorphisms?

There are 5 groups of order 8 up to isomorphism. 3 abelian ones (C8, C4xC2, C2xC2xC2) and 2 non-abelian ones (dihedral group D8 and quaternion group Q)

The numbers are 120 and 200

10 = 2*5, a product of 2 primes, and 2 divides (5-1). So there are only two groups.

Prime numbers are those numbers which are only divisible by itself Likewise, 1,3,5,7,11,13,17,19,23,,29,31,37,41,43,47,51,53,57,59. These are the only prime numbers upto 60.

2 is the only even prime number

The numbers are: (-14 + the square root 132) and (-14 - the square root of 132)

1, 8, 27, 64, 125, 216, 343

Depending on how you look at it, there are either 99 or 100 whole numbers up to 100. If you mean up to and including 100, then the answer is 100 whole numbers, if not, then the answer is 99 whole numbers.

20, 4, 4, 4. I hope you don't mean 4 unique numbers, as this seems impossible.
