Hebrew New Year with New Yerm

Palmen, KEV (Karl)
Dear Amos and Calendar People

While using
http://www.rumblefische.com/calendars/cconverter.html

I found that Yerm 10 in the current cycle of my Lunar Yerm Calendar
http://www.hermetic.ch/cal_stud/palmen/yerm1.htm
begins on a Hebrew new year's day (5769 AH) on 30 September 2008.

Also, I've known for some time that Cycle 18 (3 cycles ago) began on the Hebrew new year of 5551 AH on 9 September 1790.

Here are some examples of Hebrew New Year days with a New Yerm:

Cycle-Yerm   Hebrew NY   Gregorian Equivalent & DOW
   18-01       5551        1790-09-09  Thursday
   20-15       5707        1946-09-26  Thursday
   20-18       5711        1950-09-12  Tuesday
   20-34       5732        1971-09-20  Monday
   20-37       5736        1975-09-06  Saturday
   21-10       5769        2008-09-30  Tuesday
   21-41       5811        2049-09-27  Monday
   21-44       5814        2053-09-13  Saturday
   22-51       5892        2131-09-22  Saturday
   23-02       5896        2134-09-08  Thursday

Some of these are in pairs that are 4 years = 3 yerms apart. The pair of 20-34 and 20-37 almost forms a triplet, but 20-31 which occurs on 1967-10-04 is a Wednesday which is not allowed to be a Hebrew new year.
If a triplet does exist then,
its days of the week must be (Saturday, Thursday, Tuesday) or (Monday, Saturday, Thursday) and
its Hebrew year numbers must have remainders of (9,13,17) when divided by 19.
