摘要
第二个因子(1031-1)/9被发现是6943319与使用八辐轮[1]。辐条D(i)分别为1、7、11、13、17、19、23和29。在启动车轮之前测试了可能的因素2、3和5。常数乘数是30。可能的除数为30 * K + D(i)， K = 0,1,2,3，....该程序是用COBOL为霍尼韦尔DPS 8编写的，在CP-6下运行。选择的图片条款，使31位的十进制算术使用。执行时间约为45分钟。
A second factor of (1031-1)/9 was found to be 6943319 with the use of an eight spoke wheel [1]. The spokes D(i) were 1, 7, 11, 13, 17, 19, 23, and 29. The possible factors 2, 3, and 5 were tested prior to starting the wheel. The constant multiplier was 30. The possible divisors were of the form30 * K + D(i), K = 0, 1, 2, 3,....The program was written in COBOL for the Honeywell DPS 8, running under CP-6. The picture clauses were selected such that 31-digit decimal arithmetic was used. Execution time was about forty-five minutes.
