Requirements for developing a secret table

The secrecy of the lock is the number of combinations of pins (plates, discs) included in the cylinder mechanism, each of which corresponds only to its own key.
The number of castle secrets is expressed by a certain number.
To calculate the number of possible combinations of incisions (characterized by their depth and number) on the working face of the key, a formula is used to calculate the number of placements from n elements by so on.
The number of such placements will be:
N = n to the m power
where n is the number of drops in the notch on the working face of the key;
m is the number of notches on the key, which corresponds to the number of pins (plates) of the cylinder mechanism.
When developing secret tables for locks in each secret composition, the following conditions must be met.
For cylinder mechanisms:
- the proximity of more than two cuts with the same depth is not allowed, for example 11152, 111524, 522231;
- the presence of two pairs of cuts, in each of which both depths are the same, is not allowed, for example, 11335, 442262, 11433;
- repetition of the same cutting depth in any position of the secret more than three times is not allowed, for example 55155, 226223;
- the proximity of levels 1 and 6, 1 and 7, 2 and 7 is not allowed, for example, 141635, 3317521, 11461, 16724;
- the depth of cutting at the 3rd position (for 5-pin) and at the 3rd and 4th positions (for 6-pin) must differ from the depths of any of the adjacent grooves by at least three differences;
- if the cylinder has more than seven discs, the neighborhood of three identical cuts with the same depth is allowed.

For lever locks:
- the levels of adjacent positions, including the level of the moving bolt, must differ from each other by at least one drop;
- on the beards (beard) of the key, secrets are not allowed, consisting of combinations of a protrusion and depressions located next to it, including the level of the moving bolt, with a difference of three or more levels, for example, 125 * 521/143 * 341, 3514 * 32;
- on each of the key barbs, no more than one pair with the same levels is allowed, including the level of the moving bolt;
- the left bit of the key must not be a mirror image of the right bit.
