A{0,5}Z
In X{n,m}
the n can be zero, specifying a minimum of zero matches for subexpression X.
To ask for a match with subexpression X at least n times, use
X{n,}
(Notice that the comma is immediately followed by the right brace.)
For example, this
Rats!{2,}
matches
Rats!! Rats!!!! Rats!!!!!!
but not
Rats Rats!
Write the expression that matches two or more groups of Rats! such as Rats! Rats! or Rats! Rats! Rats! Rats!
