(a(aaa+aab+aac+aba+abb+abc+aca+acb+acc+baa+bab+bac+bba+bbb+bbc+bca+bcb+bcc+caa+cab+cac+cba+cbb+cbc+cca+ccb+ccc)^{*}a)\,\,+\,\,(b(aaa+aab+aac+aba+abb+abc+aca+acb+acc+baa+bab+bac+bba+bbb+bbc+bca+bcb+bcc+caa+cab+cac+cba+cbb+cbc+cca+ccb+ccc)^{*}b)\,\,+\,\,(c(aaa+aab+aac+aba+abb+abc+aca+acb+acc+baa+bab+bac+bba+bbb+bbc+bca+bcb+bcc+caa+cab+cac+cba+cbb+cbc+cca+ccb+ccc)^{*}c)
The strings generated are as follows:
'a' separated from 'a' by any string which is a multiple of 3
or
'b' separated from 'b' by any string which is a multiple of 3
or
