User blog comment:Kaptain Kerbab/A slightly better Array Notation/@comment-10429372-20150411155824

The a•b•1 is now good, but what about a•b•c for c>1 and longer arrays? Hint: use the # symbol for longer arrays.

However, you have made use of recursion and iteration in your notation, which is very useful. You've done better than (I think) three quarters of the newcomers, so keep up the good work!
