User blog comment:B1mb0w/Strong D Function/@comment-1605058-20150624061803/@comment-10262436-20150702133127

On a different but related note. I have two detailed blogs that suggest the same result. The "calculations" blog that explicitly claims D(3,0,0) > f_epsilon_0(3), but also this blog.

D(3,0,0) is calculated "by hand" in the blog above and a long winded f expression is shown.

D(3,0,1) is calculated in the same way. Both equations imply deep nesting in the index of the f function. This is very similar to the ordinal nesting we require when we exceed epsilon_0 and start heading towards epsilon_1 and above.

I am encouraged that both methods imply D(3,0,n) is in fact larger or perhaps comparable to f_epsilon_0(n)

I will continue to think about this.
