Ideal ring bundle (IRB) is a mathematical term which means an n-stage cyclic sequence of semi-measured terms, e.g. integers for which the set of all circular sums enumerates row of natural numbers by fixed times. The circular sum is called a sum of consecutive terms in the n-sequence of any number of terms (from 1 to n − 1).

Examples

For example, the cyclic sequence (1, 3, 2, 7) is an Ideal Ring Bundle because four (n = 4) its terms enumerate of all natural numbers from 1 to n(n − 1) = 12 as its starting term, and can be of any number of summing terms by exactly one (R = 1) way:

1, 2, 3, 4 = 1 + 3, 5 = 3 + 2, 6 = 1 + 3 + 2, 7, 8 = 7 + 1, 9 = 2 + 7, 10 = 2 + 7 + 1, 11 = 7 + 1 + 3, 12 = 3 + 2 + 7, 13 = 1 + 3 + 2 + 7.

The cyclic sequence (1, 1, 2, 3) is an ideal ring bundle also, because four (n = 4) its terms enumerate all numbers of the natural row from 1 to n(n − 1)/R = 6 as its starting term, and can be of any number of summing terms by exactly two (R = 2) ways:

1, 1 2, 2 = 1 + 1 3, 3 = 2 + 1 4 = 3 + 1, 4 = 1 + 1 + 2 5 = 2 + 3, 5 = 3 + 1 + 1 6 = 1 + 2 + 3, 6 = 2 + 3 + 1
