D4 is isomorphic, and S3 is not. When studying complex roots, the value of Q is also considered to be isomorphic.

Sodium chloride is isomorphic with potassium chloride.

similarities of heteromorphic and isomorphic generation

//not sure if it is correct

bool isomorphic(struct Node* root1,struct Node* root2)

{

if(root1 root2->value)

return ( isomorphic(root1->left,root2->left) && isomorphic(root1->right,root2->right)

isomorphic(root1->right,root2->left) && isomorphic(root1->left,root2->right)

);

else return false;

}

It has 4 subgroups isomorphic to S3. If you hold each of the 4 elements fixed and permute the remaining three, you get each of the 4 subgroups isomorphic to S3.
