clisp : remove from list of list [duplicate]

This question already has an answer here: Test if array is inside a list in lisp 开发者_Python百科 (1 answer) Closed 2 years ago.

(remove '(1 2) '((1 2) (1 3))) doesn't remove '(1 2) from list in common lisp. (I think it uses eq and not equal). Do we have any other alternative to delete element from list of lists in common lisp?

(remove '(1 2) '((1 2) (1 3)) :test #'equal)
