Pseudopremier number To summon

In Mathematical, a pseudopremier number To summon is a made up Nombre odd based on another Nombre. They can be obtained by the following process starting from a number D:

$(D^2)\; -\; (2D-1)\; +\; 1\; \backslash ,$ if D is odd

The first nine pseudopremiers numbers To summon are as follows:

1, 3, 9, 15, 25, 35, 49 and 63.

These numbers are always odd, and one can notice the reason for the figures 1-3-9-5-5-5-9-3-1. This type of Nombre pseudopremier is often confused with the pseudopremiers numbers To summon-Lucas, which have also a number P and are formed by a Suite of Lucas. The symbol for a number To summon is $S^Q\; \backslash ,$.
