When I found L(12876,2447) in early January it was the culmination of primality-checking the first 75.5 million Leyland numbers. With the addition of another computer, here I am five months later and I'm at 104.5 million. So, getting to 118.5 million in the coming months does not seem unreasonable.

I just noticed it hasn't been updated since. More importantly, the y-value of my L(14415,3274) was entered incorrectly.

Thanks for the check. I'll fix that at the next update.
