The chart included in the Microsoft Word document is a bit difficult to read, but the information about each planet's sign and exact degree may be useful to determine if Saturn is really the strongest planet in your chart.
Let's first examine the Sun: Cancer 16°44'24
- Triplicity: Mars
- Term: Mercury
- Face: Mercury
- In the succedent eighth house
Moon: Gemini 20°19'42
- Triplicity: Saturn
- Term: Jupiter
- Face: Mars
- In the angular seventh house
Mercury: Leo 13°01'23
- Triplicity: Sun
- Term: Mercury
- Face: Jupiter
- In the cadent ninth house
So Mercury seems to be the only planet so far that's in its own term, yet it's not very strong in a cadent house.
Venus: Gemini 18°13'20
- Triplicity: Saturn
- Term: Jupiter
- Face: Mars
- Angular seventh house
- Stationary (direct)
Mars Leo 6°26'47
- Triplicity: Sun
- Term: Saturn
- Face: Saturn
- Cadent ninth house
Jupiter: Capricorn 1°41'40
- Jupiter in its fall
- Retrograde
- Triplicity: Venus
- Term: Venus
- Face: Jupiter
- In succedent second house
Jupiter is in its own face, but I don't think this is nearly enough to make up for Jupiter being in the sign of its fall and retrograde...
Saturn: Gemini 14°47'52
- Triplicity: Saturn
- Term: Venus
- Face: Mars
- In angular seventh house
Saturn is in its own triplicity.
You seem to be correct that Saturn is the strongest planet in your natal chart using essential dignities, yet some astrologers also like to consider how many aspects a planet makes to determine its power, as well as to what planets this planet aspects.
The outer planets are not listed in Ptolemy's
Table of Essential Dignities, which I have been using to determine this information; therefore, I'm not going to include these planets here.

P.S. Although Saturn has accidental dignity in the angular seventh house, so do Venus and the Moon, which Saturn is conjunct; the Moon does not have any special kind of essential dignity that I can see, but keep in mind that it is "leading" the planets in your Gemini and stellium and thus, may be considered by some astrologers to have strength. Venus is also unusual in that it is stationary about to turn direct; I've read that stationary planets can be regarded as having some extra strength, too, so the process of determining the strongest planet in your natal chart is not quite as clear-cut as it may seem.
I also want to note that although Saturn has accidental dignity in the seventh house and is in its own triplicity, this is not quite as strong an influence as if Saturn were in the sign of its rulership (Capricorn or Aquarius) or its exaltation (Libra).
