495 is the integer after 494 and before 496. It is a pentatope number (and so a binomial coefficient ). == Kaprekar transformation == The Kaprekar transformation is defined as follows for three-digit numbers: # Start with a three-digit number with at least two digits different. # Arrange the digits in ascending and then in descending order to get two three-digit numbers, adding leading zeros if necessary. # Subtract the smaller number from the bigger number. # Go back to step 2. Repeating this process will always reach 495 in a few steps. Once 495 is reached, the process stops because 954 – 459 = 495. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「495 (number)」の詳細全文を読む スポンサード リンク
