  • # J, 13 char
  • ```
  • '*',^:(<_)'*'
  • ```
  • **How it works:**
  • What's in parenthesis indicates to the verb ^: that the verb to the left of ^: has to be performed to the object on the right of the ^: an infinite number of times and that it has to list each intermediate result. '_' is infinity, and '<' boxes it to force listing the intermediate results.

  • '*',^:(<4)'*'
