H is a normal subgroup of G

How do you produce the symbol for

H is a normal subgroup of a group G

I know that \triangleleft gives the symbol $\displaystyle \triangleleft$ but how do you get the symbol with equality shown as a possibility - ie a line next to the triangle sign

Be grateful for help
