0 1 -> 3 1 but the odd and even bits have been put into

2 3 2 0

different words. The main trick is to remember that

t=((l>>size)^r)&(mask);

r^=t;

l^=(t<<size);

can be used to swap and move bits between words.

Thanks for hints from Richard Outerbridge - he told me IP&FP
|
||||
could be done in 15 xor, 10 shifts and 5 ands.
|
||||
When I finally started to think of the problem in 2D
|
||||
I first got ~42 operations without xors. When I remembered
|
||||
how to use xors :-) I got it to its final state.
