In the following table the number of legal wheels is exact: other entries to four figures only.
| Total no. of wheels. |
Δ'd wheels with the correct no. of crosses. |
Legal wheels. |

| Χ3 | 535,800,000 | 78,320,000 | 14,524,128 |
| Χ4 | 66,990,000 | 19,544,000 | 2,869,568 |
| Χ5 | 8,434,000 | 1,364,000 | 556,416 |
From this table the factor in favour of a wheel because it is spontaneously legal can be calculated. It should be noticed that any supposed ΔΧ wheel corresponds to two Χ wheels or to none, so that e.g. a ΔΧ5, constrained to have the correct number of crosses gains a factor 
if it is spontaneously legal.
(R5 p 4; for factor given by integration R3 p 30.)
