I want check a string with this Patern:

Pattern.compile("^0*(([a-q]{6,}|[A-Q]{6,}){6,24})(1{6,})(([a-q]{6,}|[A-Q]{6,}){6,24})(1*0*$)");

The length of [a-q] can not be more than 6. And the length of [a-qA-Q] can not be more than 24.

For example: max 24(min 6(aaaaaa)AAAAAAAbbbbbbbbb)111111...

But the code use the group (aaaaaa) like 1 element, and should count like 6 elements. And i need use OR to [a-q]|[A-Q].

How can i do this with 1 pattern?

not sure if I understood your question correctly but try this pattern 

^(?=.*([a-qA-Q])\1{5,})[a-qA-Q]{6,24}$
