I saw this symbol: $underline{big|6} $ in a question bank for a chapter of permutations and combinations. I have included the question from the book to provide more context: image link.

That's an old symbol for the factorial of a number. It was mostly phased out by the early 1900s, but you can find it in most 1800s algebra textbooks.

This an old symbol for the factorial of a number. It was mostly phased out by the early 1900s, but you can find it in most 1800s literature, especially mathematicians in Great Britain. A useful historical survey of various notations for factorial is given in
Florian Cajori, History of symbols for $underline{n}=$ factorial, Isis 3 #3 (Summer 1921), 414-418.
