| Diophantine equation: | s2-42p2 = 1 | | | |
| d = distance to nearest square N2: | +6 | | | |
| Smallest non-trivial s: | (2*36+6)/6 | rational: 13 | actual: 13 | ⇒ F=26 |
| Smallest non-trivial p: | 2*6/6 | rational: 2 | actual: 2 | ⇒ primus foldage=2 |
| v-value qt-blocks: | 62-42*12: | -6 | | |
| Number of series: | 8 | | | |
Cross multiplying the red-green pairs renders subsequent solutions of the diophantine equation.
