Some time ago, I stumbled upon an interesting set of hypercomplex numbers. I thought that somebody else might have discovered them ( it was too facile a construction ) and forgot about them for many years. Lately, I searched on the web and did not find any mention of their existence. I must admit I did not know where to look and if they had been discovered, I did not know their name. So, being here in this great forum for a while, I am asking your permission to disclose them. Shall I go ahead? I am giving myself a 99.999% chance that they've been already known and I wouldn't bother, but am too old now to keep them for myself.
