Recursion is a procedural language concept. This is the wrong forum for this type of question. You have also not stated a question which requires recursion.

proc group_recurse { list } {
  if {[llength $list] > 1} {
    return "GRP[lindex $list 0]\n[group_recurse [lrange $list 1 end]]"
  } else {
    return "GRP[lindex $list 0]\n"
  }
}
puts [group_recurse {1 2 4 5}]
