I don't think I have a definitive answer to the IKEA question but I do know this: Founder/owner Ingvar Feodor KampradIngvar, has that type of dyslexia which results in him not being able to make much sense out of numbers. So when he was building up his catalogue he gave them all those weird and wonderful names. His problems with digits hasn't stopped him becoming the 7th richest dude on the planet, funny that.
