Publisher review:Find numbers which can be expressed as Sum of Squares of Positive Integers - Suite of 4 fns to find 2 groups of Positive Integers First, some examples :17 * 29 * 41 * 149 * 113 = 340326281= 2984^2 18205^2 = 18220^2 2891^2509 * 853 * 769 = 333882113= 11528^2 14177^2 = 18272^2 127^2The Main programme is the subfunction Test_Random_2_Squares within the function : Runs_Of_Test_Random_2_Squares_1.m which tries to find 2 sets of arrays of positive integers such that the corresponding sums of squares of the numbers in the 2 arrays equals the product of r no of Prime Factors.The function : find_the_2_Squares_from_the_Sum ( Sum ) forms the heart of this suite, which can also be independently used.Whereas, currently (Aug 2005), the top function : Runs_Of_Test_Random_2_Squares_1.mdeals only with prime factors of the form (4*n 1), the heart-function : fnd_the_2_Squares_from_the_Sum.m can still be independently used to find sum of squares - even if the factors include primes of type (4*n-1), or even 2.The various steps of the subfunction Test_Random_2_Squares.m are :1) This overall pgm first calls Prime_Fctrs_Of_Sum_Of_2_Sqrs(N)to obtain the list of primes which are
