Re: Add 13 more and post it forever.
3913 + 301 * 13 Isn't that cool?

Re: Add 13 more and post it forever.
3926 = 302 * 13 (!)
I've got V.B.'s video "Then & Now". He was brilliant: a talented pianist and terrific entertainer. Great comedian, IMHO...touched a chord with me.

Re: Add 13 more and post it forever.
3952
-3+9+5+2 = 13
-39 + 52 = 13
13 + 13 + 13 = 39, & 13 + 13 + 13 + 13 = 52
3952 appears in the concatenated list of Smith numbers at the position that is preceded by 1339 digits: 13*100 + 13*3 = 1339

Re: Add 13 more and post it forever.
3978
Applying the Victor Borge constant, 3978 becomes 41089: 4 + 10 + 8 - 9 = 13
I, too, am far too young to remember him...and if I was old enough to remember him I still wouldn't remember him because I would be too old for my memory to work well enough to remember him.

Re: Add 13 more and post it forever.
4108
4+1+0+8 = 13
The reverse of 4108 is 8014, which is a Smith Semiprime (ie, a Smith Number that is the product of two primes): 2 * 4007
And 2+4+0+0+7 = 13
91 / 13 = 7, and 4095 / 7 = 585......which is a palindrome completely divisible by 13.
585 factorizes into 3*3*5*13......and (3+3-5)*13 = 13

4134

41+34 = 75, which factorizes into 3*5*5......and 3+5+5 = 13

Re: Add 13 more and post it forever.
4186
int(10000*frac(100000*41/86)) = 4186
int(10000*frac(10^(13*2)*41/86)) = 4186
int(10000*frac(10^(13*758)*41/86)) = 4186
int(10000*frac(10^(13*(41*8+86*5))*41/86)) = 4186
4186- Post #322 = 3864......and -38+64 = 26 = 13+ 13

Re: Add 13 more and post it forever.
4199
4199 = 2^2 + 9^2 + 33^2 + 55^2
4199 = 1^2 + 1^2 + 10^3 + 10^3 + 13^3 (It is made ip of all ones and threes)
4199 = 2^4 + 3^4 + 3^4 + 3^4 + 3^4 + 3^4 + 3^4 + 6^4 + 7^4

Re: Add 13 more and post it forever.
5012
The difference between 5012 and 6123 (ie, 5012 raised by the Victor Borge Constant) = 1111......and 11+1+1 = 13.
And, what's more (moreover), is that 1111 factorizes into 11*101...and 11+1+0+1 = 13.
