      I found one that was not a semiprime, but the ratio rule still applies:
      n=41159=79*521;ratio=12
      n=45629=103*443;ratio=24
      n=64079=139*461;ratio=42
      n=96049=139*691;ratio=28
      n=197209=199*991;ratio=40
      n=228241=181*(13*97);ratio=26
      n=287051=151*1901;ratio=12
      n=330929=149*2221;ratio=10
      n=638189=619*1031;ratio=372
      n=853469=239*3571;ratio=16
      n=875071=241*3631;ratio=16

      Note: the above "n" are all +-1 (mod 5)
