revised Is this valid parametric equation to create control points for a helix in 3D space?
I'm guessing setting x to two different things was a typo; perhaps you meant z ?

@ChuckFernández: I think that was a simple typo; fixed now.

comment Boggle letter probability
+1 Good points. If your first approximation tells you to put 'A' on 6 faces, I suspect you don't want to paint all six faces of one die with the letter 'A'. That would make it impossible to form words with more than one 'a' in them, such as "attack".

comment Terminology, mapping a tree to a tree
This reminds me a little bit of some implementations of the rope data structure, where each non-leaf node stores pointers to the left-part and the right-part of the string it represents, and also stores the weight of the "string" it represents (the total of the weight of the left-part and the right-part), and several different ropes can share some of their leaves and (in some cases) a few of their non-leaf nodes.

comment Terminology, mapping a tree to a tree
This reminds me a little bit of a Huffman tree -- the "frequency value" of each non-leaf node in that tree is the sum of the "frequency value" of both of its immediate children, and it is also equal to the sum of all the "frequency values" of every leaf directly or indirectly descended from that non-leaf node.
