Hi all, I am siting with a project of making a “dwarsligger”, you know these books, printed on bible-thin-printing paper, which are about 12 x 8 cm. One opens them while holding them ‘landscape’ with the spine on the top… Now there is of course a little struggle with the page numbering. The reading page consists out of the even page together with the following uneven page. It is easy to print on the uneven page a page number, however this will result in uneven page numbers only throughout the book. My question is, whether there is an algorithm to print page numbers as follows: 1 2 3 4 5 6 7 8 9 (this is the ordinary numbering) 1 2 3 4 5 (this is the requested numbering) Does someone have an idea how to solve this? Any hints are most appreciated! Willi

Pickup n>=0, and find q and r such n = 2q + r, r = 0 or r=1
It's not clear if you have 6 what you want to print (3 or 4 ?) but playing with that formula can help you . In many times, it's better to start from zero, so it could be that you have to translate your input sequence by adding -1 and the output sequence by adding +1 .
