I'm not mathematician, english is not my language, just somewhat aging BSEE with roots into computer sciences. Now, I'm on my way searching for answers to some questions which poped in my head long time ago. Questions like "what '+' operator have in common with array substitution viewed as product of permutations", questions which all seems to be related with bijections. With a years of 'professional life' my math ignorance became amazing so what I do I do basicaly from a scratch. I like permutations, after all only a few stones are needed or a few pieces of furniture if my wife is to be asked. Be aware of my terminology :-)
