Translation help again, please

[dennis63]

This is a number from my second (and last) black belt certificate. Google translate has alternately said "No. 8" and "No. 68." I have a feeling both are wrong.

Any help would be much appreciated. Thank you in advance!

Hmm it's definitely number 6, 4 and 8 in the middle. The first character "第" refers to the particular number of something like a series, like an "8th" or "3rd". So appears to be referring to the 648th something, don't know the last character sorry..

‘Number 68’ according to Google Translate,

Thank you, Gyakuto.

I don't think Google translate is accurate in this case. I tried it and got "No. 8" and "No. 68" on two different tries. It's calligraphy, so not machine-printed. That may be complicating things or making it more difficult for A.I. to interpret it.

The certificates are issued sequentially. My Shodan certificate says Number 830. This certificate was issued 10 years later, so I'm guessing it's a number at least larger than 1,000.
