Hi and welcome to the list! Yes certainly this is the place to share

your findings, certainly myself and others would be interested in

seeing your work and the kind of progressions you are talking of.

From the Prime Pages, here's a progression that Euler came up with

over 200 years ago:

Start with

41, add 2 = 43

43, add 4 = 47

47, add 6 = 53

53, add 8 = 61

61, add 10 = 71

71, add 12 = 83

and so on for 33 more terms to yield 40 primes! All of which is the

same as the equation

x^2 + x + 41 for x=0 to x=39.

In 1998 Manfred Toplic found ten consecutive primes in arithmetic

progression:

P = 100 99697 24697 14247 63778 66555 87969 84032 95093 24689 19004

18036 03417 75890 43417 03348 88215 90672 29719,

+210, + 420, + 630, + 840, + 1050, + 1260, + 1470, + 1680 and + 1890.

I wouldn't doubt if others have found larger by now. I think it was

Phil Carmody who came up with a big one fairly recently but I don't

know how big.
