Corrected entry: For both opening the Earth gate (they mention having never gotten beyond six symbols), then opening the Abydos gate after Daniel Jackson knows the first six symbols from that cavern, why can't they simply use trial and error to find the seventh symbol? For 40-odd symbols apiece on both, it would only take approximately that many guesses by process of elimination.

Corrected entry: The premise for Jackson going on the mission is that once on the other side someone would need to be able to re-open the gate using new symbols, but in reality it would just be a matter for earth to re-open the gate from their end at a predetermined time or times.
Correction: The gateway is a one way trip, you can't go back through the wormhole when the gate has been opened from the other side.
Pure assumption. We don't know exactly how the stargate works. It may actually be possible to go back through the stargate, even if you just came through and it was still open. We just don't know.
It has been well established that Stargate travel is one-way.
Since when?
After Jackson says he doesn't know how to dial back, when they are setting up camp, Brown says "if we're not back soon, they'll just turn on the gate from the other side", and Ferretti tells him "no, it doesn't work that way, you see, if you don't turn it on from here, we're screwed." The one way travel is also stated in the later TV series.
Since always.
Correction: This mistake has already been corrected, twice. The military in control of the project might not have allowed them to experiment with different symbols simply because they didn't know what it might do. Not fully far fetched since the entire compound starts shaking when entering the 6th symbol. It might explode for all they know.

Then the Abydos gate alone. Six symbols down. One to go. 40 odd guesses, easy enough, less than an hour.

You missed the point of the correction. It could have been 4 options and still not worth the risk of entering the wrong symbol.

Well, we don't know if the gate on Abydos makes everything shake. So, I'd say there is a point there. But they only discover the symbols on Abydos till later. By then, they are already at the tribe, I think.
