摘要:

摘要:
We show that isomorphic subrings of the ring L of integer quaternions necessarily have the same index as additive subgroups of L. We then show how to find this index for idealiser subrings of L, and determine the number of isomorphism-classes of certain types of subrings of matrix rings over L.
