RFC 3526 defines the MODP Diffie-Hellman groups.

Where 3526 fits
Why 3526 is special
The Logjam work showed that a handful of these groups were used almost universally, so precomputing against one broke a large share of the internet's key exchanges.

In historical numeral systems
Egyptian
3 lotuses, 5 coils of rope, 2 hobbles, 6 strokes
3 × 1,000 + 5 × 100 + 2 × 10 + 6 × 1 = 3,526. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 corner wedges + 8 vertical wedges (sixties place), 4 corner wedges + 6 vertical wedges (units place)
58 × 60 + 46 = 3526. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
Reuse of a small set of standardised Diffie-Hellman groups is what made precomputation attacks against many connections worthwhile.

Technology & computing
RFC 3526 specifies standardised MODP groups for Diffie-Hellman. Because implementations reused a small set, precomputation against a single group could compromise many independent connections.
