Si valores pro x et y inventi vel in n ga 
vel in n= 23y +11 substituantur habebitur 
n= 115r — 35. 
Sub hac formula comprehensi sunt omnes nu 
meri, quibus desideratae proprietates compe 
tunt, et qui prodibunt, si pro r numeri natu 
rali ordine progredientes (nimirum 1, 2, 3, 
4, 5, etc. in infinitum) substituantur. Horum 
omnium minimus invenitur, ponendo r= 1. 
Ille erit = 115— 35 — 80.
