The S scale SIG is an NMRA-affiliated special interest group dedicated to promoting and providing information on scale model railroading at 1:64. The National Association of S Gaugers serves as an organization to promote all forms of S gauge model railroading.
S scale, NZR W class locomotive from New Zealand Finescale. Sn3½ is the primary scale for modeling New Zealand's narrow gauge 3 ft 6 in railways. The majority of rolling stock available, are white-metal kits, making them considerably more expensive and heavier than other scales and countries. Many of these kits are highly detailed.
The gist of the RG is this group property: as the scale μ varies, the theory presents a self-similar replica of itself, and any scale can be accessed similarly from any other scale, by group action, a formal transitive conjugacy of couplings [4] in the mathematical sense (Schröder's equation).
Note that a "complex Lie group" is defined as a complex analytic manifold that is also a group whose multiplication and inversion are each given by a holomorphic map. The dimensions in the table below are dimensions over C. Note that every complex Lie group/algebra can also be viewed as a real Lie group/algebra of twice the dimension.
The group Spin(3) is isomorphic to the special unitary group SU(2); it is also diffeomorphic to the unit 3-sphere S 3 and can be understood as the group of versors (quaternions with absolute value 1). The connection between quaternions and rotations, commonly exploited in computer graphics, is explained in quaternions and spatial rotations.

Rivian trades at just 3.2 times sales, while rivals Lucid Group and Tesla trade at around 10 and 14 times sales, respectively. To be sure, Lucid Group also remains unprofitable, unlike Tesla.
