Mar 22, 2018 at 12:28 | comment | added | Shalom | @GerryMyerson I am aware that they almost always should tend to involve as small as possible number of smallest primes, it is a question how long will 3 be a factor of at least one of a numbers that are smallest examples, I do not know how long. | |
Mar 22, 2018 at 12:26 | comment | added | Gerry Myerson | It is not surprising, is it, that the smallest example involves the smallest primes? | |
Mar 22, 2018 at 12:20 | comment | added | Shalom | @GerryMyerson But it is of 7314, so of a two numbers in our smallest examples at least one has 3 as a factor, so far. | |
Mar 22, 2018 at 12:11 | comment | added | Gerry Myerson | The smallest example for $k=4$ is $7315-7314=1$ (and 3 is not a factor of 7315). | |
Mar 22, 2018 at 12:08 | comment | added | Shalom | @GerryMyerson And the smallest examples, so far, for $k=1,2,3$, all three have $3$ as a factor of a bigger number, and $2$ as a factor of a smaller number. | |
Mar 22, 2018 at 12:03 | comment | added | Gerry Myerson | The smallest example for $k=3$ is $3\cdot7\cdot11-2\cdot5\cdot23=231-230=1$. | |
