 2019-01-06, 12:38 #134 garambois     "Garambois Jean-Luc" Oct 2011 France 677 Posts OK, updated web page. My own calculations: 3^178, 3^190, 3^192, 3^194 and 3^200 up to 120 digits. @gd_barnes Base 14 added and reserved for you. I found a merge for 14^7 but not for 14^13 ! @all Don't forget to check the mergers. Thank you all !

 2019-01-06, 20:39 #137 gd_barnes     May 2007 Kansas; USA 17·617 Posts You updated a few hours too soon! I started on base 14 late yesterday. My plan was to post an update today. Here it is: All even exponents <= 104 have terminated. Odd exponent merges: 14^7 term 21 merges with sequence 2484 term 9 with a value of 106640 14^13 term 262 merges with sequence 167748 term 33 with a value of 5933240 Odd exponent non-trivial terminations: 14^5 terminates at term 3478 with P=43 after reaching 88 digits 14^9 terminates at term 373 with P=59 after reaching 23 digits 14^19 terminates at term 378 with P=7 after reaching 30 digits 14^21 terminates at term 339 with P=7 after reaching 25 digits 14^23 terminates at term 362 with P=43 after reaching 32 digits 14^25 terminates at term 225 with P=43 after reaching 30 digits All open sequences with exponents <= 26 have reached size >= 102 and cofactor >= 97. I'll post a final status update when I am complete with the base. Perhaps 3-6 days. Last fiddled with by gd_barnes on 2019-01-06 at 20:39
 2019-01-06, 22:35 #138 gd_barnes     May 2007 Kansas; USA 17·617 Posts 14^31 term 1396 merges with sequence 65208 term 6 with a value of 1619928.
 2019-01-07, 06:21 #139 gd_barnes     May 2007 Kansas; USA 17×617 Posts 14^35 and 14^37 both non-trivially terminate. Base 14 is a prolific base for terminations and merges. Last fiddled with by gd_barnes on 2019-01-07 at 06:21
 2019-01-07, 11:29 #140 gd_barnes     May 2007 Kansas; USA 17×617 Posts The run of terminations continues. 14^45 terminates.
 2019-01-07, 17:35 #141 garambois     "Garambois Jean-Luc" Oct 2011 France 2A516 Posts Really beautiful ! I will wait a few days before updating the page.... during the next weekend. Then the situation will have stabilized.
 2019-01-09, 15:49 #142 gd_barnes     May 2007 Kansas; USA 1048910 Posts Base 14 all exponents <= 104 is complete to at least size 102, cofactor 97. Highlights: All even exponents have terminated. Merges as previously posted: 14^7, 14^13, and 14^31 Odd exponent terminations as previously posted: 14^5, 14^9, 14^19, 14^21, 14^23, 14^25, 14^35, 14^37, 14^45 Additional termination: 14^57 terminates at term 664 with P=1429 after reaching 80 digits. The base is released. This was a prolific base. 64 / 104 exponents terminated = 61.5%. It is the 2nd best base > 2 so far searched. Stats: Base 28: 51 / 82 = 62.2% Base 14: 64 / 104 = 61.5% Base 11: 68 / 115 = 59.1% Base 14 just missed 1st place when 14^91 starting at 105 digits dropped all the way to 17 digits before returning to its original height. Perhaps bases divisible by 7 or 14 have naturally more terminations than the others. Last fiddled with by gd_barnes on 2019-01-09 at 16:14
