In many places, I found that two words unlike English.

Gemini and Triton, if I remembered correctly.

As far as I know, Triton is the former product name of BaaN product family. For example, Triton 1.0, 2.0 and 3.0. And then, BaaN IV, BaaN ERP and SSA ERP LN. Right?

But What Gemini mean?

Any post ofr this threat will be highly appropriated.

Yes, Triton is the old product name for Baan in Versions below IV. I think there was a trademark conflict (with Intel?), so Baan changed it.

gemini was a codename for one of the Baan V versions.

gemini was a codename for one of the Baan V versions.
I think its something like this -

BaaN-5a : Greig
BaaN-5b : Verdi
BaaN-5c : Corelli
BaaN-5.2a, b : Reger (Tools Version 7.3)
BaaN-6.0 : Gemini (Tools Version 7.5) - Invensys Ownership
BaaN-6.1 : SSA_ERP_LN (Tools Version 7.6a, 7.6a1) - SSA Ownership

I never got to work with Tools Version 7.4 as it was never released to customers.

Nice list, but not completely correct.
5.0b = Grieg
5.0c = Corelli
5.1a = Verdi
5.2a = Reger
6.0a = Gemini
6.1a1 SP1 = Matrix
6.1a2 SP2 = Radius (not yet released)
