There is nothing called SubGroup so refer to SubGrp instead which is what must have been meant.
This is all three syntaxes and df-subg , df-nsg , and df-eqg
Stated as in set.mm. The proof needs some intuitionizing but is basically the set.mm proof.
Restricting a group to its base set.

This is ifeq2da from set.mm with a decidability condition added. The proof is based on the iset.mm proof of ifeq1dadc . Correct comment for ifeq1dadc to reflect our conventions.
Stated as in set.mm. The proof needs intuitionizing in several places but is basically the set.mm proof.
This is issubg2 from set.mm with non-empty changed to inhabited. The proof needs intuitionizing but is basically the set.mm proof.

The intuitionizing here is pretty easy for the most part. Only one theorem needs to be stated differently and of those proofs which need to change, it isn't in especially big ways.
