I find the sequence below a trifle mystifying. Why the jump from 5 -> 
36? Given how it works I would expect to see a linear progression up from 5.

And then there is a test at the top, before all this, that says "if this 
number >= 20 then stop recursing". So how come it's still recursing?

These are all rhetorical questions (not expecting answers [although if 
anybody cares to tell me where I am going wrong, I shan't mind]).

I *shall* get to the bottom of this, else rewrite it to achieve the same 
result by iteration. Just not this evening, it will have to wait till 
tomorrow.
