# Mathematical permutation drawing/visualization tool

I'm writing software and need to document an existing mathematical permutation in our code.

I thought the folks here would know where I can find a drawing/visualization tool to draw a permutation tree.

$a$b        \$c
true   true      true    134
true   true      false   245
true   false     true    2
true   false     false   3
false  true      true    8
false  true      false   17
false  false     true    19
false  false     false   32

What's a permutation tree? –  Yuval Filmus Jun 5 '11 at 19:56

I think this might be what mostly is called a "decision tree". It might be a better question for programmers/SE since no math or software development is involved. –  hardmath Jun 5 '11 at 20:13
