To get the size of an expression, convert it into De Bruijn index then count the number of lambdas / backslashes and numbers. By example, <code>(\1 1) (\\2 (1 2))</code> is size 8 because it has 3 backslashes and 5 numbers. For n ≤ 7, BBλ_db(n) = n is trivial and can be achieved via picking any size n term already in normal form, like BBλ(m) for m ≤ 20. {| class="wikitable" !BBλ_db(n)...") Tag: Visual edit
