Building a character in Fallout 4 gives you 28 points in total to assign to your SPECIAL attributes during the initial character build - compared to 40 points in Fallout 3/ Fallout New Vegas.
In Fallout New Vegas you could increase your SPECIAL attributes over the course of the game via temporary buffs but you could also permanently increase your attributes using perks and implants. Using all available perks and implants there was a maximum of 61 SPECIAL points available (reference: http://fallout.wikia.com/wiki/Fallout:_New_Vegas_SPECIAL#Notes )
I realise it's day one and we've all got a long way to go but hopefully someone else can answer this question before I can:
How many permanent SPECIAL points are available in Fallout 4?
