• PART

part of the Theory of Numbers (see NUMBER) . We consider in it a number as made up by the addition of other numbers: thus the partitions of the successive numbers 1, 2, 3, 4, 5, 6, &c., are as follows: I; 2 , I I ; 3, 2I, III; 4, 31, 22, 21I, III1; 5, 41, 32, 311, 221, 2II1, 1I1I1; 6, 51, 42, 411, 33, 32I, 311I, 222, 22II, 2IIII, See also:

• FORM (Lat. forma)

form the partitions of 6 we take first 6; secondly, 5 prefixed to each of the partitions of I (that is, 51); thirdly, 4 prefixed to each of the partitions of 2 (that is, 42, 411); fourthly, 3 prefixed to each of the partitions of 3 (that is, 33, 321, 3111); fifthly, 2 prefixed, not to each of the partitions of 4, but only to those partitions which begin with a number not exceeding 2 (that is, 222, 2211, 2111 I) ; and lastly, r prefixed to all the partitions of 5 which begin with a number not exceeding 1 (that is, 1r11 1I); and so in other cases . The method gives all the partitions of. a number, but we may consider different classes of partitions: the partitions into a given number of parts, or into not more than a given number of parts; or the partitions into given parts, either with repetitions or without repetitions, &c . It is possible, for any particular class of partitions, to obtain methods more or less easy for the formation of the partitions either of a given Thus a See also:
