1. Tempering any two consecutive square-particulars S''k'' and S(''k''+1) will naturally imply tempering the ultraparticular between them (S''k''/S(''k''+1)), meaning they are very common implicit commas. | |||
2. Tempering any two consecutive ultraparticulars will imply tempering the [[#Sk/S(k + 2) (semiparticulars)|semiparticular]] which is their sum/product. A rather-interesting arithmetic of square-particular (and related) commas exists. This arithmetic can be described compactly with '''S-expressions''', which is to say, expressions composed of square superparticulars multiplied and divided together, using the Sk notation to achieve that compactness. | |||
3. Tempering the ultraparticular S''k''/S(''k''+1) along with either the corresponding 1/2-square-particular S''k'' * S(''k''+1) or one of the two corresponding lopsided commas S''k''<sup>2</sup> * S(''k''+1) or S''k'' * S(''k''+1)<sup>2</sup> implies tempering both of S''k'' and S(''k''+1) individually, and vice versa, so that there is a total of ''five'' equivalences — corresponding to ''five'' infinite families of commas — for every such S''k'' and S(''k''+1). This only gets better if you temper a third consecutive square-particular. This is an abundance of "at a glance" essential tempering information that is fully general so only needs to be learned once, and is the motivation of the use of '''S-expressions'''. (For example, {S16, S17} => {S16 * S17, S16/S17, S16<sup>2</sup> * S17, S16 * S17<sup>2</sup>}, and any of the two commas in the latter set imply all the other commas too!) | |||
