1) Deveraj has no Thoerem.
2) Devaraj has no theorem, either.
3) Pomerance (not Pomernce) and
4) Alekseyev (not Maxal) showed that
5) merely half of a conjecture by Deveraj holds,
6) while the other half is patently false
7) and hence can have no corollary.
Any advance on 7 mistakes?
- Dear Maxmilian,
Let me clarify;
A 104016 is the sequence of Devaraj Numbers
which are also Carmichael
Numbers and A 104017 is that of Devaraj Numbers which are NOT CNs. Both
display a property of
Let me clarify; A 104016 represents Devaraj numbers which are CNs and
A104017 represents DNs which are not CNs. best illustrated by following
Let us take 561, the smallest CN.
My conjecture about this is that 2*560/10*16 is
an integer ( and so it is =7).
Now let us take the smallest in the seq A 104017 viz 11305=5*7*17*19
My conjecture: 4*11304*11304/6*16*18 is an integer and so it is.
As regards my site if it is not accessible I wd be only too happy to send
the relevant file as an attachment/
Trust I have made myself clear.

PS: the posts 2e4 and 2e4-1 are empty since you cannot send attachments. But we have the Pomerance-Alekseyev proof at http://www.mersenneforum.org/showpost.php?p=55271
