Hello My name is Sara Ferrari, i'm an italian student and i'm starting to use Mathematica . The problem to solve is to generate a serie of numbers that must respect the follow condition: the numbers are 9 from 1 to 9 The random serie is long 9^11 every subserie (of 9 numbers)can't have the follow disposition: 1 2 3 4 5 6 7 8 9 and all the 9x8x7x6x5x4x3x2x1 dispositions where all the 9 numbers exit in a serie of 9 long. The same condition must be respect every 2-3-4-x- selection ,where the selectio between the 9 numbers has the same distance. 1_2_3_4_5_6_7_8_9 ( _ ) = numbers (DISTANCE 1) 1_ _ 2_ _ 3_ _ 4_ _ 5_ _ 6_ _ 7_ _ 8_ _ 9 (DISTANCE 2) and so on. Which is the code that i must to insert in mathematica for generate the serie above indicate ? Thanks Sorry for my bad english... a kiss for who can help me Bye
