Henry Ernest Dudeney/Puzzles and Curious Problems/272 - A Madam Problem

Puzzles and Curious Problems by Henry Ernest Dudeney: $272$

A Madam Problem

In how many different ways is it possible to read the word $\text {MADAM}$ in the diagram?

You may go as you please, upwards and downwards, forwards and backwards,

any way possible along the open paths.

But the letters in every case must be contiguous, and you may never pass a letter without using it.
